The smoke barrier 2 is movable in the front-rear direction along the bottom 11 of the smoke collecting hood 1 so as to open and close the air intake 112. The shape of the smoke baffle 2 corresponds to the bottom 11 of the smoke collecting cover 1 and is in a curved arc shape. The bottom 11 of the smoke collecting cover 1 and the arc of the smoke baffle 2 are both upwards protruded, the front end of the bottom 11 of the smoke collecting cover 1 is lower than the rear end, and the front end of the smoke baffle 2 is lower than the rear end.

Referring to fig. 2 to 6, a first sliding groove 111 is formed in the bottom 11 of the smoke collecting cover 1, a guide rail 3 extending in the front-rear direction of the smoke collecting cover 1 is arranged on one side of the bottom 11 of the smoke collecting cover 1 facing the inner side of the smoke collecting cover 1, the extending direction of the guide rail 3 is consistent with that of the smoke blocking plate 2, and the position of the guide rail 3 corresponds to the first sliding groove 111.

The smoke baffle 2 is connected with the guide rail 3 through a connecting piece 4 which can slide relative to the guide rail 3. The guide rail 3 is provided with a second slide groove 33, and the connecting member 4 is provided with a slider 41 slidable in the second slide groove 33 in the guide rail 3. The top and bottom of the guide rail 3 are respectively formed with a first opening 31 and a second opening 32 that are aligned with the extending direction of the guide rail 3, and the first opening 31, the second opening 32, and the second chute 33 are penetrated. One end of the connecting element 4 passes through the second opening 32 at the bottom of the guide rail 3 and the first sliding groove 111 to be connected with the smoke barrier 2, and the other end of the connecting element 4 extends out of the first opening 31 at the top of the guide rail 3 and slides relative to the first opening 31.

Referring to fig. 4, in order to automatically drive the connecting member 4 to slide relative to the guide rail 3, the range hood further includes a driving device 5 and a transmission device 6 driven by the driving device 5, both of which are disposed in the smoke collecting hood 1, and the transmission device 6 is connected to a portion of the connecting member 4 extending out of the first opening 31.

The transmission 6 includes a transmission wheel set 62 and a timing belt 63. The transmission wheel set 62 includes a first transmission wheel 621 located at the front side of the fume collecting hood 1 and a second transmission wheel 622 located at the rear side of the fume collecting hood 1. The first driving wheel 621 and the second driving wheel 622 are fixed on one side of the guide rail 3 through the bracket 64, and the first driving wheel 621 and the second driving wheel 622 are connected through the timing belt 63, and the end of the connecting member 4 away from the smoke barrier 2, i.e., the portion extending out of the first opening 31 is connected to the timing belt 63.

The driving means 5 comprises a motor for driving the first driving wheel 621 or the second driving wheel 622.

In this embodiment, in order to make the smoke barrier 2 move smoothly, the guide rail 3, the first sliding groove 111 and the connecting member 4 are provided in two sets, respectively located at the left and right sides of the smoke collecting hood 1 near the edges. The transmission 6 further includes a synchronizing bar 61 driven by the motor and extending in the left-right direction. The transmission wheel sets 62 are provided with two sets, which are respectively positioned at the left and right sides of the synchronizing bar 61 and near the guide rail 3. Both ends of the synchronization rod 61 are connected to the first driving wheel 621 or the second driving wheel 622 on both sides, so as to drive the first driving wheel 621 or the second driving wheel 622 to rotate. One motor is used to drive the rotation of the synchronization lever 61, and the rotation shaft extends in the left-right direction, and the same rotation shafts of the first driving wheel 621 and the second driving wheel 622 also extend in the left-right direction.

Referring to fig. 7, when the range hood is in a shutdown state, the smoke baffle 2 is almost completely located below the smoke collecting hood 1, the air inlet 112 is closed, the distance between the front end of the smoke baffle 2 and the installation wall surface of the range hood is L1, preferably, the value range of L1 is about 330mm, and compared with the traditional ceiling-mounted range hood, the smoke collecting hood 1 has a small front-back depth and is not easy to touch. The distance between the lowest end of the smoke baffle 2 and the cooker 100 is H1, preferably, the value range of H1 is about 510 mm. The distance between the lowest end of the smoke baffle 2 and the top of the cooking bench 200 is H2, preferably, the value range of H2 is about 670 mm.

Referring to fig. 8, when the range hood is in the on state, the smoke barrier 2 moves to the front of the smoke collecting hood 1 to open the air inlet 112, a distance between the front end of the smoke barrier 2 and the installation wall surface is L2, and preferably, a value range of L2 is about 450 mm. The distance between the lowest end of the smoke baffle 2 and the cooker 100 is H3, preferably, the value range of H3 is about 300 mm. The distance between the lowest end of the smoke baffle 2 and the top of the cooking bench 200 is H4, preferably, the value range of H4 is about 470 mm. At the moment, a large deep cavity is formed between the range hood and the mounting wall surface, so that the negative pressure region can be obviously moved downwards while the range hood has a good smoke collecting effect. Because the smoke baffle 2 moves forwards and downwards, under the condition of ensuring the internal cooking space, a physical smoke baffle screen which is about 300mm away from the cookware 100 is formed, compared with the distance between the smoke collecting cavity of the traditional top suction type range hood and the cookware about 500mm, the position of 200mm lower part of the smoke collecting cavity where the oil smoke is most prone to drift provides powerful smoke separation, smoke collection and anti-interference capabilities, the oil smoke suction effect of the top suction type range hood is greatly improved, and the adaptability to different kitchen environments is also improved. In addition, the high-temperature oil can be prevented from splashing to the face when food is fried.
